Digestion

Disaccharide

A double sugar, consisting of two monosaccharides.

Enzymes are

A group of chemicals in the body helps to control a wide variety of chemical reactions including the breakdown into simpiler substances.

Saliva contains a chemical substance that breaks down some of the starches in food into sugars in the mouth

Amylase

Solid wastes exit the body through this opening....

Anus

The three functions of a digestion process are...

Breaks down food, absorption and eliminates waste.

Formula for glucose...

C6 H12 O6

What is chemical digestion?

CD = chemical process, salivary glands, (Amylase)

Pepsin

Chemical digestion is aided by the enzyme contained in Gastric juice

The process if breaking down food into small nutrient molecules is called _____________.

Digestion

protein that speeds up a chemical reactions in the body is an __________. Chemical digestion accomplished by these proteins.

Enzyme

After you swallow, smooth muscles force food into the tube that transports food from the mouth to the stomach

Esophagus

Digestive Process...

Food enters the mouth, moves through the esophagus and into the stomach.

How does fiber aid digestion?

Helps food move along, provides the bulk needed

The body's largest and heaviest organ that produces bile aids in digestion.

Liver

What is mechanical digestion?

MD = physical movement, teeth

Small intestine

Most digestion takes place in the organ that is more than 6 meters log and only 2.5 cm in diameter.

Pancreas

The soft, triangular organ that produces insulin that is important in controlling the body's use of sugar.

when you swallow food, a flap of tissue called the __________________ seals off your windpipe.

epiglottis

The _____________ connects the mouth to the stomach.

gall bladder

What happens to the water contained in the materials that pass into the large intestine?

gets absorbed in the blood stream.

Contains bacteria that feed on material passing through

large intestine

large intestine

prepares wastes for elimination from the body

Produces bile

liver

Polysaccharides

many sugars

___________ is a thick, slippery substance that lines the esophagus.

mucus

Involuntary waves of muscle contractions that keep food moving in one direction through the digestive system are called ___________________.

peristalsis

Monosaccharides are

simple sugars

Is directly attached to the stomach

small intestine

Most absorption of nutrients occurs here

small intestine

Most chemical digestion occurs here

small intestine

Receives bile and enzymes from other organs.

small intestine

is lined with villi

small intestine

Most mechanical processing of food occurs in the _____.

stomach

The process of ______________ involves the movement of nutrients through the wall of your digestive system into your blood.

absorption

Breaks up fat molecules

bile

Produces enzymes that flow into the small intestine

Pancreases

Structure in which waste material is compressed into solid form

Recutm

Food undergoes mechanical and chemical digestion in the J-shaped organ that releases a fluid called gastric guice.

Stomach

Tiny singer-shaped structures in which absorption occurs...

Villus

Peristalsis

Waves of rhythmic muscular contractions push food through the digestive system.
